The sealing layer 23 effectively seals the gap between the photovoltaic panel and the mounting plate 19, thereby improving the waterproof effect, effectively preventing rainwater from penetrating and moisture from accumulating, and improving the power generation efficiency and service life.

[0029] In another aspect, the water is preliminarily collected by the multiple groups of second drainage grooves 6 and is guided to the first drainage groove 4.
